Major upheavels and stunning changes to Jupiter’s atmosphere.
Must be the carbon burning space probes.
The presence of methane, a hydrocarbon, on Jupiter must be “proof” that dinasaurs once roamed Jupiter! Today a substantial amount of the earth’s petroleum deposits may very well be composed of recycled ancient plants and animals, but I happen to believe that planets in our solar system having the elements hydrogen, carbon, oxygen, and sulfur also have a mechanism for creating petroleum from them even if these elements were not associated with plant or animal life. Thus it may be entirely possible that the earth’s petroleum supply is not finite because the total amounts of these elements are unchanging.
